Cam upgrade for my truck, '72 D200 with a 360
So plugging in some numbers in online calculators, it looks like the Lunati cam I linked actually has slightly earlier IVC point than the stock 2-bbl cam just based on advertised duration numbers I could find (and assuming LSA and ICL of 112???). I do understand the importance of keeping that number low to maximize cylinder pressure with stock low compression.
My other question is regarding lifters, I watched Uncle Tony's video about flat tappet lifters and how to check the face for having the correct crown. From what I can tell, all the lifters sold by the bigger cam companies come from the same supplier and it can be hit-or-miss on quality. Has anyone bought a flat-tappet cam and lifters recently and had any issues? What brand(s) did you go with? I'm leaning towards just getting lifters that come in a cam & lifter kit from the same company and check them carefully with a mic and a flat pane of glass, usually it's part of their warranty to use their specified lifters in case a lobe/lifter gets boogered during break-in. If any are out of spec I'll take pics and either send back for replacement or look at other options. Not really trying to spend $400 on a set of Hylift-Johnsons for a truck engine.
FWIW the Voodoo cam I ran previously I installed and broke-in in 2009 with Lunati hydraulic lifters from a kit, lasted 25,000-odd miles in 2 engines with no failures. It was still even in decent shape when I pulled it from the last engine but decided to toss it due to mileage and it did have slight visible wear on the lobes.
